Title: Fire retardant membrane switch
Inventor: SAOTOME YUTAKA
IPC: H01H13/06
Filed: 1988-06-27
Abstract: PURPOSE:To enhance the fire retardancy without causing drop of the printing suitability by forming an electrode sheet from a laminate film, in which an adhesive layer containing fire resistant powder is interposed between polyester films. CONSTITUTION:Each electrode sheet 1, 1 consists of a laminate film, in which an adhesive layer 12 containing fire resistant powder is interposed between polyester films 11, 11, wherein the fire retardancy can be further enhanced by forming a spacer film 2 also from a laminate film. In such a laminate film either non-spreaded or spreaded film can be used as polyester film, and the thickness shall favorably range 12 thru 75mum. The thickness construction of the laminate film shall have an appropriate thickness share of adhesive layer, which depends upon the fire retardancy as required, and it is normally around 20% of the total thickness of plastic film. This accomplishes excellent fire resistant property, which together with non-existence of any fire resistant material on the surface of polyester film, forms no obstacle for the printing suitability of electroconductive patterns.

Title: Refrigerating cycle for low temperature
Inventor: YASUDA HIROSHI
IPC: F25B7/00
Filed: 1988-06-29
Abstract: PURPOSE:To raise the reliability of a refrigerating cycle for generating low temperature and make it possible to generate stable low temperatures by combining two sets of refrigerating cycles which employ a mixture coolant in the fashion of a cascade. CONSTITUTION:A mixture of coolants R22 and R13 which is discharged from a compressor 1 is cooled in a condenser 2 by water or air to be separated in gas phase coolant almost all the composition of which is R13 and liquid phase coolant almost all the composition of which is R22. A mixture of coolants R503 and R14 which is discharged from a compressor 8 is cooled in a condenser 6 by the low temperature in the order of -65 deg.C which is generated by an evaporator 6 of the cycle on high pressure side, and R503 which has a high boiling point is liquefied, and the mixture of coolants is separated by a gas and liquid separator 9 to a liquid phase coolant with R503 being its main composition and gas phase coolant with R14 being its main composition. With this arrangement it is possible to cool efficiently the condenser in the cycle on the low pressure side by the low temperature obtained by the cycle on the high temperature side so that is possible to obtain low temperature stably by an evaporator in cycle on the low temperature side.

Title: Formation device of two-color picture
Inventor: KAMEYAMA TOMOHIRO
IPC: G03G15/01
Filed: 1984-07-31
Abstract: PURPOSE:To prevent the 1st picture from disturbance at the 2nd development or a photosensitive substance from the adhesion of a carrier or the like and to obtain a two-color picture of high quality by carrying a developer for the 2nd develoment on a nonmagnetic sleeve in the reverse direction against the turning direction of a parmanent magnet roll. CONSTITUTION:At the time of development, the developer forms two developing layers consisting of an upper layer 22 moved on a nonmagnetic sleeve 17 by the rotational magnetic field of the parmanent magnet roll 16 rotating in the clockwise direction while turning on its axis and a lower layer 23 similarly moved in the counterclockwise direction by the frictional force with the surface of the nonmagnetic sleeve 17. The developing layers are regulated so as to be kept at a fixed layer thickness by a doctor blade and contact a photosensitive substance 1 to attain development. Since the flow of the developer is fixed in one direction when the parmanent magnetic roll 16 and the nonmagnetic sleeve 17 are rotated in the reverse directions each other, the developer is not dispersed and the carrier can receive magnetic force easily from the roll 16 because there is no reverse flow of the development, so that the carrier is not almost adhered to the photosensitive substance 1.

Filed: 1994-06-20
Abstract: PURPOSE:To enable locking in the intermediate position of opening/closing action by inserting a pin, provided at an opening/closing hinge, into the loop part of a fixed hinge, and bringing the contact face into contact with the loop part at the rotating time of the opening/closing hinge so as to limit its rotation. CONSTITUTION:The hinge structure is constituted of the fixed hinge 1 fixedly provided at floor material, an opening/closing hinge 4 fixedly provided at the front end part of a partition plate, and a pin 8 for connecting the fixed hinge 1 and the opening/closing hinge 4 to each other. A loop part 3 with a loop 2 is formed at the center part of the fixed hinge 1, and a stopper part 6 with the contact face 5 is formed at the corresponding position of the opening/closing hinge 4. In this case, the opening/closing hinge 4 is rotated to move the pin 8 downward in the loop 2, and the contact face 5 is inclined. The opening/ closing hinge 4 is further rotated to lower the pin 8 downward in the loop 2, and the contact face 5 comes in contact with the side face 9 of the loop part 3 to limit the rotation of the opening/closing hinge 4. The opening/closing hinge 4 is thereby locked in the intermediate position of opening/closing action, and small articles can be easily put in/out in the locked state of the opening/ closing hinge 4.

Abstract: PURPOSE: To form the active layer of Si with matched lattice distance, by making γ-Al 2 O 3  with Si or Mg by 10 17  to 10 21  atoms/cm 3  doping.  
     CONSTITUTION: The atom diameter of Mg is smaller than that of Al, and that of Si is greater. Accordignly, when the doped Si atom gives the strain extending the crystal lattice of γ-Al 2 O 3 , this strain is occupied with smaller Mg and the crystal is made stable by absorption and buffering. The vacant lattice point of Al atom for γ-Al 2 O 3  not added is present about 10 20  to 10 22  atoms per 1 cm 3 . Then, at least one of Mg or Si is doped by 10 17  to 10 21  atoms/cm 3 , the vacant lattice point is  burried  with the doped atoms and it is stable thermally. When the extent is exceeded, the crystality is deteriorated with the polarization of doped atoms. Further, the  Si active  layer is formed on it, then epitaxial growing is made with good lattice  alignment.

Title: Dimming device provided with moving sensor
Inventor: SHIMIZU NORIZOU
IPC: G03B27/72
Filed: 1982-09-14
Abstract: PURPOSE:To keep the intensity of light of a light source constant overall, by performing dimming on a basis of the average intensity of light of the light source which is detected from the whole of the light source. CONSTITUTION:An optical sensor 3 is attached loosely onto a shaft 6 of a light source 1. The sensor 3 has one end fixed to a chain 7 or the like and is driven by a motor 5. Then, the motor 5 is driven in accordance with the signal from a controller 2, and the chain 7 is moved in accordance with this driving to move the sensor 3 on the shaft 6. Thus, the sensor 3 detects the intensity of light throughout the whole of the light source 1. The signal of the detected intensity of light is inputted to the controller 2 and is integrated in the controller 2, and electric power to the light source 1 is controlled in accordance with the integral value to keep the intensity of light constant. Thus, since dimming is performed on a basis of the average intensity of light of the light source which is detected from the whole of the light source, the intensity of light is kept constant overall, and the variance between sensors is not generated because the single optical sensor is used.

Abstract: PURPOSE:To attain a switch having no polarizing property, by providing parallel electrodes for each of two waveguides on a substrate to form splitters which cross in two positions and coupling mode lights, which are separated by the input-side splitter, in the output-side splitter again. CONSTITUTION:With respect to the incident light from a lower waveguide 8 of the input side, the TE mode light and the TM mode light are turned to a lower waveguide 12 and goes straight to an upper waveguide 13 respectively from an input-side splitter 9. Both lights are coupled again in an output-side splitter 10 and go to a lower waveguide 14. When an electric field is applied in the horizontal direction to upper and lower waveguides 13 and 12 to perform the mode conversion, the advance direction of lights coupled again in the output-side splitter 10 is switched, and thus, light switching without the modal noise due to polarization dependence and 3dB loss is realized.
